我的代码曾经在 Django 1.3 中工作,但在更新到 Django 1.4 之后它不再工作了。这个想法是为 django-admin-tools 构建一个 MenuItem,其中包含来自应用程序的模型列表。

from admin_tools.utils import AppListElementMixin
from app import models as my_models

class CustomMenu(Menu):
    def init_with_context(self, context):

        app_list=AppListElementMixin()

        '''ERROR not working after upgrade to django 1.4, returns empty list'''
        all_models = get_models(app_mod=my_models)
        ''''''

        dict_models = {}
        for model in all_models:
            dict_models[model.__name__] = items.MenuItem(
                                            title=model._meta.verbose_name_plural,
                                            url=app_list._get_admin_change_url(model, context)
                                            )

尝试将您的“应用程序”添加到 settings.py INSTALLED_APPS 然后执行此操作

from django.db.models import get_models, get_app

和这个

all_models = get_models(app_mod=get_app('app'))

如果您的目标是为每个模型添加一个菜单项,您可以尝试:

from django.core.urlresolvers import reverse
from django.utils.translation import ugettext_lazy as _

from admin_tools.menu import items, Menu

class CustomMenu(Menu):
    def __init__(self, **kwargs):
        Menu.__init__(self, **kwargs)
        self.children += [
            # Other items that are in the menu eg "items.Bookmarks()," go here
            items.AppList(
                _('Name of the submenu'), # Your own choosing
                models=('app.models.*',) # Assuming your django app is called "app"
            )
        ]

    def init_with_context(self, context):
        return super(CustomMenu, self).init_with_context(context)

这就是我在我的一个项目中所做的工作。
